HAY-CARRIER.

Specification of Letters Patent.

Patented Sept. 30, 1913.

To all whom it may concern Be it known that we, D D MILLER and DAVID E. ROWLAND, citizens of the United States, residing at'Canton, in the county of Stark and State of Ohio, have invented certain new and useful Improvements in Hay- Carriers, of which the following is a specification.

Our invention relates to parallel draft hay carriers, that is hay carriers in which the elevating rope leads from the carrier in a direction substantially parallel with the track along which the carrier is adapted to move, said elevating rope being employed not only to elevate the load to the carrier but also to draw the carrier along the track to the place of discharge.

The objects of our invention are to generally improve devices of the character mentioned, to provide a parallel draft hay carrier in which the plane of the fall of the rope will be transverse with respect to the length of the track and the direction of the elevating rope leading from the carrier, to provide a parallel draft, transverse-fall hay carrier in which the weight of the load will be evenly distributed with respect to the two sidesof the carrier and in which the main sheave of the carrier is arranged in vertical alinement with the center of the track and in a plane parallel therewith.

Further objects of the invention are to prevent the twisting or Winding of the parts of the fall of the elevating rope between the carrier and load when the carrier is in operation, the more perfect operation of the load sustaining device while the carrier with load suspended is drawn along the track to the place of discharge, to provide means for more accurately and positively locking the carrier to the stop block and unlocking it therefrom and to increase the general efficiency of hay carriers of this type.

These objects, together with other objects which will be apparent to those skilled in the art, we attain by the construction illustrated in the accompanying drawings, al-

though our invention may be embodied in other forms of construction, that form illustrated being chosen by way of example.

In the drawings Figure 1 is a perspective view of a hay carrier embodying our invention mounted upon the track, the parts being in the position assumed when the load is suspended, the elevating rope locked and the carrier free from the stop block. Fig. 2 1s a vertical sectional view of the same carrier showing the parts in the same position as shown in Fig. 1, the stop block on the track being also shown in elevation. Fig. 3 1s a rear end View of the carrier, the track being shown in crosssection. Fig. 4 is a fragmentary elevation of the inner side of the forward end of one of the frame members. Fig. 5 is a vertical sectional view of the carrier illustrating the position of the parts when the carrier is locked to the stop block and the elevating rope unlocked. Fig. 6 is a detached perspective view of the trip yoke. Fig. 7 is a detached perspective view of the looking dog. Fig. 8 is a detached perspective view of the main rope-locking lever with the movable rope grip connected thereto. Fig. 9 is a fragmentary perspective view of the inner side of one ofthe frame members where the trip bar is slidably connected to said member at its upper end.

Throughout the several views similar reference numerals indicate similar parts.

The numeral 1 indicates the track which may be of any suitable or well known form bar 3 provided at its two ends'with the rotatably mounted traveling wheels 4 adapted to run upon the track 1. In this way it will 5 be noted that the carrier with its load is suspended from eight traveling wheels, two i trucks being arranged at the front and two i at the back. Substantially midway between j the forward and rear trucks and in the lower portion of the main frame is arranged the main sheave axle 5 which extends transversely from side frame to side frame and upon which is rotatably mounted, preferably with a roller bearing, the main sheave 6. This main sheave is preferably of considerable diameter to lighten the draft as much as possible, overcome friction and facilitate the operation of the carrier. It should be noted that the median plane of said main sheave is substantially identical with the vertical, median, longitudinal plane of the track 1 and the main frame.

Pivotally connected to the sides 2 and 2 upon a transverse bearing having its axis at 7 is the rope locking lever having spaced forward extending portions 8 and spaced real-wardly extending portions 9 of relatively greater length than said forward extending portions, the axis 7 being considered as the dividing point between said front portions and rear portions. The rear portions 9 are united at their rear ends and preferably provided with a knot socket 10 to receive the end knot of the elevating rope, a lateral rope aperture 11 through which the elevating rope extends to the fall and with a cross bar 12, the purpose of which will hereinafter fully appear. At the forward ends of the front portions 8 the movable rope grip 13 is pivotally connected intermediate its ends upon a transverse pivot at 14, the upper face of the rope grip 13 being provided with a longitudinally extending grooved surface provided with cross ribs 15 for engagement with the rope.

Located above the rope grip 13, normally parallel therewith, and fixedly connected to the sides 2 and 2 is the stationary rope grip 16 provided with a longitudinally ex tending groove on its under side opposite the grooved upper face of the grip 13. The grip 16 is preferably connected to the sides 2 and 2 by a transverse bolt 17 and by means of the lugs 18, formed integrally with the grip 16, arranged between the projecting flanges 19 formed upon the forward portion of the sides 2 and 2". It will be understood that when the rear portion 9 of the rope locking lever is moved downwardly the front portions 8 with the rope grip 13 will be moved upwardly toward the grip 16 for the purpose of locking the elevating rope 2O bet-ween them, as will hereinafter be more fully explained.

Upon the transverse bolt or other bearing 21 extending from the frame 2 to the frame 2 is pivotally mounted the locking dog which is provided with the integral transverse trip-yoke-engaging bar 22 and with the lever lifting hook 23. Said lever lifting hook engages the cross bar 12 at the rear end of the rope locking lever as clearly illustrated in Figs. 2 and 5. The hook 23 is so disposed with reference to the axis of rotation of the locking dog that when the dog is rocked into its backward position illustrated in Fig. 2 the cross bar 12 will be permitted to move downwardly, permitting the rear end of the rope locking lever to be lowered. When, however, the locking dog is rocked into the upper position illustrated in Fig. 5 the hook 23 moving upwardly and forwardly around the axis of the bolt 21 will carry the cross bar 12 upwardly, thus raising the rear end of the rope locking lever and loweringthe front portion 8, as illustrated in Fig. 5. It will be noted that when the locking dog is rocked into its back ward position and the cross-bar 12 moves downwardly, said cross bar 12 will move out along the hook 23 away from the bearing 21. As the locking dog is rocked into its upper position the cross bar 12 slides inwardly along the hook 23 toward the hearing 21 so that the farther the bar 12 is raised the less resistance will the locking dog offer to rotation into its upward position.

For the purpose of maintaining the locking dog in the upper position as illustrated in Fig. 5 the trip yoke shown in Fig. 6 and also in Figs. 2 and 5 is provided. Said trip yoke comprises the upwardly and forwardly extending spaced arms 24 and the integral arm connecting portion 25, said portion 25 being preferably provided with an axial opening through which extends a hollow sleeve 26 which is held in place transversely between the sides 2 and 2 by the bolt 27. It will be understood that the sleeve 26 serves to hold the sides of the frame in proper spaced relation while providing a suitable bearing upon which the trip yoke may pivotally move.

At their extreme forward ends the arms 24 are provided with flanges 28 preferably i11- wardly turned and having inclined upper and lower faces for the purpose hereinafter fully described. Adjacent their forward ends and on the undersides of said arms 24 looking recesses 29 are provided, which looking recesses are adapted to receive the transverse extending bar 22 of the locking dog when said locking dog is in the upper position illustrated in Fig. 5. 7

Upon the track 1 directly above the place where the hay is to be lifted to the carrier from the wagon is arranged a stop block 30 provided with a dependent bumper portion 31 and with the integral lateral bumper flanges 32, the under faces of which are upwardly inclined from the rear to the front, as illustrated in Figs. 2 and 5. The stop block may be connected to the track in any suitable way as by the bolts 33 and top plate 34, or in any other well known manner.

Attention should be called to the bumper 35 forming an integral portion of the locking dog. When the locking dog is in its backward position, permitting the rear end of the rope locking lever to be lowered the bumper 35 will stand upwardly in its most elevated position as illustrated in Fig. 2. WVhen said bumper 35 is in said elevated position and the carrier caused to travel backwardly along the track 1 said bumper 35 will engage the bumper portion 31 of the stop block, and the momentum of the carrier causing the same to move slightly farther backwardly, the locking dog will be rotated upon the bolt 21, thus raising the hook 23 and lifting the rear end of the rope locking lever and throwing the bar 22 into its upward position illustrated in Fig. 5, whereupon the arms 24 of the trip yoke will drop downwardly, seating the ends of the bar 22 within the locking recesses 29 and thus preventing any backward rotation of the locking dog. It should be noted that when the bar '22 rises to its upward position, as illustrated in Fig. 5, it engages the rear side of the bumper portion 31 of the stop block, thus preventing any forward move ment of the carrier along the track 1.

Normally the arms 24 will drop by gravity so as to engage the bar 22, said bar lifting said arms slightly as the locking dog is rotated and said arms dropping downwardly as soon as said bar has reached the locking recesses 29. To insure the proper dropping of said arms 24 however the upper inclined faces of the flanges 28 are adapted to engage the lower inclined faces of the bumper flanges 32 so that as the carrier moves backwardly along the track 1 and immediately after the bumper 35 has engaged the bumper portion 31 and rotated the look ing dog into the position illustrated in Fig. 5 said flanges 28 and flanges 32 will cooperate to move the arms 24 downwardly if they do not so move freely or sufficiently quickly by gravity. This feature insures the absolutely certain locking of the carrier to the stop block which feature is of great importance in the satisfactory operation of hay carriers. It should be noted that the arms 24 are of sufficient length so that the flanges 28 will not engage the bumper flanges 32 until the carrier has moved slightly backwardly beyond the position illustrated in Fig. 5, the locking dog in fact being rotated slightly farther than illustrated in Fig. 5 and the bar 22 passing slightly beyond the'bumper portion of the trip block. When the arms 24 have dropped into their locking position so that the bar 22 is located in the recesses 29 the carrier may then move forwardly slightly until the bar 22 engages the bumper portion ofthe trip block as shown in Fig. 5, thus slightly freeing the flanges 28 from the bumper flanges 32 so that the arms 24 may be slightly lifted without interference by the stop block when said arms 24 are en'- gaged by the trip bars presently to be described. Vertically slidably mounted in the sides 2 and 2 are the trip bars 36, said trip bars being held in place by offset angled lugs 37 formed integrally with said sides as illustrated in Figs. 2 and 9 and said sides being also provided with vertically disposed inside recesses at 38 to slidably receive said trip bars. The upper ends of the trip bars 36 are provided with trip yokeengaging flanges 39 adapted to engage the lower faces of the flanges 28 of the trip yoke when said bars 36 are slidably moved upwardly.

At their lower ends the trip bars 36 are connected to the fall guiding frame 40 which is preferably provided with two vertical transverse slotted apertures separated by the division piece 41, the two vertically disposed apertures being adapted to accommodate the two sides of the fall of the elevating rope, as clearly illustrated in Figs. 1 and 3.

At the rear lower portion of the carrier frame the guiding pulleys 42 and 42 are rot-a'tably mounted upon longitudinally dis posed spindles, said pulleys being arranged substantially above the outer portions of the two slots of the fall guiding frame respectively.

At the extreme forward portion of the main frame the guiding pulley 43 is rotatab'ly mounted upon a transverse spindle, said pulley being adapted to permit the elevating rope to travel over it 'as said rope leaves the carrier.

In reeving the carrier a knot 44 should be tied at one end of the elevating ro-p'e 20, said knot being arranged in the knot socket 10 as illustrated in the drawings. Extending from said knot the rope passes outwardly through the lateral rope aperture 11 in the rear end of the rope locking lever and downwardly on the inner side of the guiding pulley 42", through the rope aperture of the fall guiding frame 40 immediately below said pulley 42 thence downwardly and through the lifting head or heads of the fork, sling or other hay engaging device. In the drawings I have illustrated the carrier as in use in connection with hay slings of well known construction, the hay sling pulleys 45 constituting the lifting head in such instance. Extending upwardly from the lifting head the rope passes through the other aperture in the fall guiding frame, past the pulley 42* which it lightly engages, up and over the main sheave 6, out frontwardly between the movable grip 13 and stationary grip 16, lightly engaging the guiding pulley 43 and thence, parallel with the track 1 to the forward end of staid track where it passes over a guiding pulley and thence downwardly and, if necesary, through other guidingg pulleys 'to the point where the horses are ment of the load. When the load is attached the elevating team is driven forward, drawing the elevating rope forwardly and raising the load toward the carrier. It will be noted that substantially one-half the load will be supported by that side of the fall which is attached to the rear end of the rope locking lever, but the locking dog being held in raised position prevents the rear end of said lever from descending. Then the load has been elevated sufiiciently so that the elevating head engages the fall guiding frame 40 further slight elevation of the load will slidably move the trip bars 36 upwardly whereupon the trip yoke engaging flanges 39 will engage the under faces of the flanges 28 of the trip yoke. Further slight elevation of the load will force the arms 24: of the trip yoke upwardly, thus releasing the bar 22 from the locking recesses 29, whereupon the forward pull upon the carrier acting through the stop block, as well as the weight of the load upon the rear end of the rope locking lever will cause the locking dog to instantly rotate into the backward position illustrated in Fig. 2, freeing the carrier from the stop block and permitting it to move forwardly along the track 1 and at the same time permitting the rear end of the rope locking lever to descend and throwing the movable rope grip 13 upwardly to clamp the elevating rope between said grip and the stationary grip 16 as illustrated in Fig. 2. The load will thus be sustained during the travel of the carrier forwardly along the track 1 to the place of discharge of the load and in fact until said carrier is returned in the usual manner to the stop block. The carrier arriving upon its return at the stop block, the bumper 35 engaging the bumper portion 31 will rotate the locking dog, raising the rear end of the rope locking lever, locking the carrier to the stop block as illustrated in Fig. 5, and permitting the elevating rope to run backwardly between the unlocked rope grips and over the main sheave 6 and permitting the sling or other hay engaging device to descend to the wagon. At the time when the bumper 35 engages the bumper portion 31 the cross bar 12 will be at the outer limit of its movement on the hook 23, away from the bearing 21 and the sudden impact of the bumper 35 against the bumper portion 31 will greatly lessen the momentum of the carrier and will partly rotate the locking dog, bringing the cross bar 12 in nearer the bearing 21. The further, slackened movement of the carrier will further rotate the locking dog and the resistance against rotation of said locking dog will be lessened by reason of said cross-bar being nearer the bearing 21. This construction is thus adapted to somewhat cushion the shock of the returning carrier against the stop block and at the same time is adapted to cause the locking dog and the rope locking lever to perform their functions in a more perfect manner.

It should be noted that by reason of the peculiar construction herein described the weight of the load while being elevated and transferred in the mow is evenly distributed to the two sides of the carrier.

It should also be noted that the transverse position of the plane of the fall of the rope is maintained at all times while the main sheave is rotatably mounted in a median longitudinal plane and that the elevating rope at all points is guided and directed in such way and by such means as to prevent injury to saidrope when the carrier is being operated and to produce the lightest possible draft for the elevating team.

Attention should also be called to the very positive locking and unlocking features of the carrier and to the fact that our invented hay carried is a general improvement over hay carrier is a general improvement over bodies many features of great value which will be appreciated by those skilled in the art to which our invention belongs.
